How to reset a rca l40fdh41yx9

Is there a software reset on a flat panel RCA television? I have a 46" RCA flat panel tv and no matter what input you try to use, the screen says "no signal." All the menus work fine, but you can't hook up anything, cable, dvd, component, hd, anything. Please help me, I can't reset it, I heard that you could unplug it to reset it, but that does nothing whatsoever, it has stayed unplugged for days, and nothing helps. Thank you very much!

SOURCE: "weak signal" on my RCA scenium

Hey! I have the same problem as you. But! this would happen only when I got a power outage. Unplug the TV for a couple of minutesand all was fine. For the last 5 day I have no TV. I have tried everything. All the out on the TV and I still get unusable signal. My rep told me to unplug for 24 Hours. Still didn't work. My menu option work as well and every time I put the TV on, off or if I change the input sound will come on for 2 seconde and stop. If I find the salution I will let you know. Gilles Ottawa

SOURCE: RCA L46WD22 LCD tv (3 year-old unit)...No picture,

The back lights inverter is working because you can see the "Unusable Signal' on the screen, if the inverter is dead, yoo will see nothing on the screen at all.
If the T-CON (LCD controller) is dead, you will see just gray glowing screen with no pictures or text.
You may have problem with video processor in the main logic board (tuner, audio, source selector).
Parts for your TV:

This is going to be difficult repair since you do have a way to try out the replacement board to be sure that is the problem. RCA service person has that advantage of parts in stock to try out.
I estimate the board from Jimmy to be about $150, from RCA will be twice as much, plus labor.

Please see my basic troubleshooting guide here:

Hi are you getting any flashing codes from the power light or is it steady. These codes tell us what is going on. The main reason on these sets that cause a condition like this is the power supplies going bad. these are just circuit boards that regulate the power for the set and they tend to overheat and eventually go bad. Have you had the cover off and looked at the boards for any damage, bad capacitors or burn marks?

Using a box of some kind? try unplugging that and wait then plug back to see if the issue is the box. It will try to reboot.
